xutil3 post 和 get请求

https://i.cnblogs.com/EditPosts.aspx?postid=7001253

compile 'org.xutils:xutils:3.3.36'

注册xutil3

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

实例化x，创建application，在oncreate方法中加入

 @Override

    public void onCreate() {

        // TODO Auto-generated method stub

        super.onCreate();

        x.Ext.init(this);

        x.Ext.setDebug(BuildConfig.DEBUG); // 是否输出debug日志, 开启debug会影响性能.

    }

这步千万别忘记了applicaiton声明，ApplicaitonData是我创建的applicaiton的名称

android:name=".ApplicaitonData"

activity oncreate代码

 x.view().inject(this);

Fragment  oncreate代码

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        return x.view().inject(this, inflater, container);

}

使用方法post请求

public void postData(){

        dialog.show();

        String url="http://route.showapi.com/138-46";

        RequestParams params = new RequestParams(url);

        params.addBodyParameter("showapi_appid","38170");

        params.addBodyParameter("showapi_sign","");

        params.addBodyParameter("prov","");

        x.http().post(params, new Callback.CommonCallback<String>() {

            @Override

            public void onSuccess(String result) {

                System.out.println("+++++++++:onSuccess"+result);

                Message message = new Message();

                message.what = 1;

                handler.sendMessage(message);

            }

            @Override

            public void onError(Throwable throwable, boolean b) {

                System.out.println("+++++++++:onError:"+throwable);

                Message message = new Message();

                message.what = 2;

                handler.sendMessage(message);

            }

            @Override

            public void onCancelled(CancelledException e) {

                System.out.println("+++++++++:onCancelled");

            }

            @Override

            public void onFinished() {

                System.out.println("+++++++++:onFinished");

            }

        });

    }

get请求

public void getData(){

        dialog.show();

        String url="http://route.showapi.com/138-46";

        RequestParams params = new RequestParams(url);

        params.addQueryStringParameter("showapi_appid","38170");

        params.addQueryStringParameter("showapi_sign","");

        params.addQueryStringParameter("prov","");

        x.http().get(params, new Callback.CommonCallback<String>() {

            @Override

            public void onSuccess(String result) {

                //解析result

                System.out.println("+++++++++:onSuccess"+result);

                Message message = new Message();

                message.what = 1;

                handler.sendMessage(message);

            }

            //请求异常后的回调方法

            @Override

            public void onError(Throwable ex, boolean isOnCallback) {

                System.out.println("+++++++++:ex:"+ex);

                Message message = new Message();

                message.what = 2;

                handler.sendMessage(message);

            }

            //主动调用取消请求的回调方法

            @Override

            public void onCancelled(CancelledException cex) {

            }

            @Override

            public void onFinished() {

                System.out.println("+++++++++:onFinished:");

            }

        });

    }

Image使用

/*

        通过ImageOptions.Builder().set方法设置图片的属性

        ImageOptions imageOptions= new ImageOptions.Builder().setFadeIn(true).build(); //淡入效果

//ImageOptions.Builder()的一些其他属性：

        .setSquare(true) //设置图片显示为正方形

                .setCrop(true).setSize(200,200) //设置大小

                .setAnimation(animation) //设置动画

                .setFailureDrawable(Drawable failureDrawable) //设置加载失败的动画

                .setFailureDrawableId(int failureDrawable) //以资源id设置加载失败的动画

        .setLoadingDrawable(Drawable loadingDrawable) //设置加载中的动画

                .setLoadingDrawableId(int loadingDrawable) //以资源id设置加载中的动画

        .setIgnoreGif(false) //忽略Gif图片

                .setParamsBuilder(ParamsBuilder paramsBuilder) //在网络请求中添加一些参数

                .setRaduis(int raduis) //设置拐角弧度

        .setUseMemCache(true) //设置使用MemCache，默认true

 */

        imageView = (ImageView)findViewById(R.id.imageView);

        ImageOptions imageOptions = new ImageOptions.Builder()

                .setImageScaleType(ImageView.ScaleType.CENTER_CROP)

                .setRadius(DensityUtil.dip2px(5))

                .setIgnoreGif(false)

                .setCrop(true)//是否对图片进行裁剪

                .setFailureDrawableId(R.drawable.ic_launcher)

                .setLoadingDrawableId(R.drawable.ic_launcher)

                .build();

        x.image().bind(imageView, "http://ytjr.gnway.cc:88//upload/YS01/img/4144148607704755a547da45dd15a473.png", imageOptions);
